1. Apparatus for controlling a fluid flow;
- comprising;
a housing having at least three fittings for connection of three tubular elements;
valve means rotatably secured in the housing and indexable in various predetermined positions for selectively establishing a fluid communication between the fittings, said valve means including a rotatable grip outside of said housing and a blocking element inside of said housing and connected to the grip, said blocking element formed with lateral openings and a passageway for allowing a fluid flow between two of the three fittings at one time; and
at least one closure member received in the housing and associated to one of the fittings, said closure member being acted upon by the valve means for linear displacement in a radial direction to open and close a passage through said one fitting.

Abstract
Apparatus for controlling a fluid flow includes a housing having a first fitting for connection of a tube and at least one further fitting for detachable securement of a coupling piece of a peritoneal catheter. Accommodated in the housing is a rotary valve which is indexable in predetermined positions to selectively establish a fluid communication between the fittings. Associated with one of the fittings is at least one closure member which is acted upon by the rotary valve for displacement in a radial direction to open and close a passage to the peritoneal catheter.

13. A method of using an apparatus as connector for peritoneal dialysis, said apparatus comprising a housing having a first fitting for securement of a tube, a second fitting for seucrement of a second tube, and a third fitting for detachable securement of a coupling piece of a peritoneal catheter, valve means rotatably secured in the housing and indexable in various predetermined positions for selectively establishing a fluid communication between the fittings, said valve means including a rotatable grip outside of said housing and a blocking element inside of said housing and connected to the grip, said blocking element formed with lateral openings and a passageway for allowing a fluid flow between two of the three fittings at one time, and at least one closure member received in the housing and associated to one of the fittings, with the closure member being acted upon by the valve means for linear displacement in a radial direction to open and close a passage through the one fitting, said method comprising:
-
connecting a peritoneal catheter, a drain bag, and a source of irrigation fluid each to one of said three fittings; dialyzing a patient by indexing the connector to permit flow from the source of irrigation fluid to the connector; and indexing the connector to permit flow from the catheter to the drain bag.
